CASH-REGISTER.

State of Ohio, have invented certain new and useful Improvements in Cash-Registers,

of which Iv declare the following to be a full,

clear, and exact description.

This invention relates to improvements in cash registers, certain of these improvements relating to the so-called multiple counter type of machine, and has among objects to provide novel forms of devices 1n connection with-the setting mechanism for actuating the accounting devices, also certain improvements relating to the operation'of the various counters including certain locking mechanisms utilized therewith.

With these and incidental objects view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a'preferred form of embodiment of which is hereinafter specifically described with' reference to the drawings which accompany and 'form part of this specification.

Vnism between the bank of clerks keys and the multiple counter setting lever. Fig. 10 represents aA detail viewof the special 'counter actuating mechanism.` Fig. 11 represents a detail view of the' counter mechanism. y v

Certain of the mechanisms associated with -applicant von Sept. 12, 1903, Serial No. 172,970, such for example as theindicator throwout/ the improvements set'lforth in the present. application are similar to those described. in a co-pending application filed by the same" vmechanism, and the setting and the operat- Ving mechanism or the grand'total counter;

but certain improvements have been incor porated'in the present application in connection with the settin of the various differential elements which actuate the accounting devices, as well as different feab tures associated with the multiple counter mechanism, the characteristic featurev of which will be fully set forth presently.

The key-board is arranged in the .ordi-L nary manner with five banks of amount keys 20 (see Fig. 1) and a .bank of clerks Vkeys 21. Power is applied to the machine by means .of a crank handle 22'wl1ich as, v shown in Fig. 2V operates` through gear' wheels 23, 24, 25 and 26. to impart a com' -plete-v revolution at each 'operation of the -machine to an upper operating shaft 27 and a lower operating shaft 28, the direction of rotation of the various gears being shown by arrows."

Setting mechanism.-The shank of each key 20 carries a pin 30 (see Fig. -4f) which cooperates with a detent plate 31 having the usual beveled nose and angle slot to hold the key in depressed position. This datent plate 31v carries a rearwardly projecting arm 32 Vformed with a latching nose 33V which Vengages over a lug 34ormed upon Vthe side of a bell crank lever 35 which is pivotedV loosely upon a transverse shaft 36'and hasa forwardly extending arm 37 having' a slot and diierent angles so as to give different extents of movement to the stop any key is depressed and itsA '1n enters said plate when slot.4 A spring 40 presses agalnst the aforesaid lever 35 so that it tends to throw .the

upper arm of the same rearward. When any key is depressed the operation of its detent plate 31 releases the latch from the lug 34 and permits the lever 35 to spring rearward under its spring tension. The consequent upward movement `of the arm 37 slides the stop plate 38 vertically. upward and as the key continues its depression the pin thereof enters the slot 39. The stop plate 30 is of course limited in its movement by the nal setting of the key at the bottom of its slot 39, so that the differential inclinations of said slots will resultjin the differential movements of the lever 35 according to the key depressed. It will be observed from Fig. 4 that for the key pin 30 of the highest key in the bank (which is the 1 key), there is no slot 39 but the stop plate 38 simply ends at thisl point and its upper end is slightly inclined so that upon the movement of the l key the stop plate may move sufhciently to cause the lever to be set for one degree of. movement.

The inner ends ofthe key Shanks may be so arranged with reference to the lever 35 that they will strike said lever and move the same positively to differential extents, the extent of movement of course bein absolutely limited by the stop plate 38;. ut the presence of the spring 40 takesthe work off of the keys in that as soon as the key is depressed and the lever 35 unlatched the spring 40 tends to set the lever to proper position without requiring the added pressure on the keysto eilect this setting movement. There is one of these setting levers 35 for each bank of keys andfor convenience they will be designated as the primary setting elements, the mechanism being such as to restore these elements to normal osition after they have been set diferentialiy' by the keys and this movement of restoration is utilized to set secondary setting elements as will now be set forth.

Situated near the upper end of eachv of the levers 35 is a link 41 (see Fig. 3) formed on its lower side with rack teeth 42 and also provided with a slot 43 through which extends a transverse vibrating rod 44. Teeth 42 are arranged to mesh with a segmental plate 45 fast upon the side of a bell crank segment 46 having at its upper end a segmental rack 47 and at its lower end another segmental rack 48. The rack 47 meshes with a pinion 49 carried by a sleeve on a transverse shaft 50, there of course bein one of these pinions 49 for each bank o keys and if it is desired their sleeves may :extend through one side of the machine to serve as connections for operating the type wheels but such a printlng attachment will not be described in the present case since it constitutes no part of the present invention.

The aforesaid segmental racks 48 mesh with teeth 51 on the lowerend of the vertical setting bar 52 near the forward u per end of which is a rack bar 53 arrange to actuate the main total counter 'as will be later described, and this same bar 52 is valso utilized to leffect the setting of the corresponding indicator. Meshing with each pinion 49 .1 s an intermediate segment 54 mounted upon a sleeve turning on a transverse shaft 55. As shown in Fig. 8a these sleeves are connected by nested yokes '56 with setting gears or segments 57 (see also Fig. 8). Below these setting gears 57 are a series of rack bars 58 (see Fig. 8). The rearward end of each bar 58 is formed with a slot 59 surrounding a transverse shaft 60 which acts as a guide and support for the rack bar, and the forward end of the bar is formed with a slot 61 through which extends a transverse vibrating rod 62. This rod extends transversely between two arms of a rocking frame, one of these arms 63 being shown partly in dotted lines in Fig. 8, and pivoted upon a transverse shaft 64. The downwardly extending portion of the arm 63 carries a pin 65 projectin into a cam groove 66 formed in a disk 67 ast upon an operating shaft 68, which shaft as shown in Fig. 2 receives a complete revolution at each operation of the machine by means of the gear wheel 69 which meshes with the aforesaid gear wheel A24. These rack bars 58 are for the purpose of actuating any desired one of a series of multiple counters as will later be described, and on the lower side of each rack bar is a rack 70 for operating such multiple counters and on the :upper side is a rack 71 adapted to mesh with the aforesaid setting ears 57. In the normal position of rest o the machine, the rack 71 is out of mesh with its corresponding settin gear 57; but upon the o eration of the mac ine, the rotation of the s aft 68 causes the disk 67 to act upon the arm 63 and raise the vibrating cross rod 62 so as to throw the racks 71 into mesh withl the setting gears 57 at a certain point in the o eration of the machine so that these rack ars 58 will then be enabled to partake of the setting movement of the setting gears 57.

The means for giving the setting movement to the gears 57 is as follows: The aforesaid vibrating cross rod 44 (see Fi 3) is carried between the arms of a rocd g frame which as shown in Fig. 11 is pivoted at S1 and is operated by'means of an arm 82 extending upward therefrom andcarrying a pin 83 projecting into a cam oove 84 formed in a disk 85 fast upon Ie upper operating shaft 27. Normally the ibratlng rod 44 stands in its up er position so as to maintain all of the lin 4l raised so that their rack teeth 42 are out of mesh with the segmental plates 45, and thus when any key is depressed and the primary settin elements or levers 35 are carried rearwar the links 41 will be carried rearward certain differential extents according to the keys depressed; now upon the operation of the machine, the cam groove 84 operates to vibrate the cross rod 44 downward and thereby carry the rack teeth 42-into mesh with the segmental plates 45 so that the links 41 are thereby locked to the bell crank segments 46. The primary setting levers 35 are now 1 positively restored to normal position by means of a transverse shaft 90 extending betweenian arm 91'pivoted loosely upon the aforesaid transverse shaft 36 and an arm 92 (see Fig. 6) also pivoted loosely upon said shaft 36. This arm 92 has attached to it a link 93 carrying at its rearward end a pin 94 running in a cam groove 95 formed in a disk 96 fast upon the lower operating shaft 28, the'shape of the cam groove being such A24) that upon the operation of the machine the arm 92 and cross rod 90 are rocked forward and thereby any levers 35 which have been operated and carried rearward differentially, are now positively restored to normal forward-position; and since the links 41 are at this time coupled to the bell. crank segments 46, these segments are moved to a distance .exactly corresponding to the extent of movement of restoration of their corre- Bo-sponding setting levers 35. `This differential extent of movement ofthe bell crank segment`46 servesto setthe vertical bar 52 differentially and-likewise through the pinion 49, intermediate gear Y54, yoke 56 and 3.5 setting gear 57 serve to set the secondary setting element or rack bar 58 differentially to the same extent, the said rack bar 58 having at this time been thrown up into mesh with said setting gear 57. Thus it .will be seen that. the secondary setting elements or rack bars 58 are set differentially to distances'correspon'd'ing to the values of the keys depressed, through the process of restoring the primary setting elements or levers to normal zero position,- which restoration is effected by the operation of the machine, so that in this manner the secvondary setting elements do not have to be set by the actualforce applied by the depreion of the key but are set subsequently upon the loperation` of the machine, and now by throwing these secondary rack bars 58 out of mesh with their setting gears 57, these rack bars 58 may then in turn be restored to normal=lzero position, andnby throwing the rack bars into mesh with their accounting devices which in this case are the multiple counters presently to be described, this restoration of the' 'secondary setting elements 58 to normal position may be utilized to actuate said accounting devices. This restoration of the rack bars 58 to normal position is effected by means of a vibrating rod 100 (see Fig. 8) carried between arms 101 extending downward from counters w the transverse shaft 102, and an. arm 103 carrying a pin 104 is acted upon by a c am bars 58 by striking against a projection 106 extending upward therefrom, this restoration of course taking place subsequent to the rearward dierential setting movements of said racks. As Soon as the arm 103 has been cammed downward in this 'mannen the weight of the vibrating rod and its supporting arms cause the arm 103 'to return to normal upper position as shown in Fig. 8 as soon as the disk 105 has been given a com plete rotation. The aforesaid belly crank segments-16 are also restored to normal position at each operation of the Y machine, with -their lower sides resting upon the transverse shaft as shown in Fig.V v3. This: restoration to normal position is effected by means of a vibrating rod lllcarried between arms 112 pivoted upon the same shaft 113 to which the segments 46 are mounted. .As shown in Fig. 5 there is attached to one lof these arms 112 a link 1 13aL which at its rearward end carries a pin 114 extending into a cam groove 115 formed in a disk 116 fast upon the lower operating shaft 28, so that upon the. operation of the machine the cross rod 111 will be drawn rearward to restore the segments 46 tonormal position against the cross bar 110,` and then the rod 111 is immediately thrown forward again to permit the differential movements of said segments 46 when the Ysetting levers 35 are restored to normal position 1n the manner above described. It will beobsetting gears 57.' As soon asthe segments' 46 and setting gears 57 are restored to normal position in this manner, thevibrating rod 44 is operated as above described to connect the `levers 35 tothe segmentslirand the vibrating rod 62 is operated to carry the' rack bars 58 into mesh with their segments 57 so that the aforesaid setting movements of said rack barsv 58 will now take place in the manner described. As soon as this setting movementof the rack bars 58 has been eifected, said rack bars are then carried downward by the vibrating rod 62A into mesh with the particular one of the mul.-

'ch has been brought into' vious that this restoration ofthe segments' i vposition tobe operated in the 'manner to be presently described, and after such operation of the multiple counter the rack bars 58 are iinally thrown out of mesh with said is'counters so as to permit the setting movements of said rack bars upon the next operation of the machine, the normalA position of 'said rack bars 58vbeing as shown in Fig. 8. s Key release-Since it is necessary to release the depressed keys before the Asetting levers-35 can be restored to normal osition, a keyrelease mechanism is provided as follows: For each key detent 31,2(see Fig. 6), there is a pin 120 projecting Afrom-.the end of the same and extending between the jaws of a rock arm 121 fast toa rock shaft 122. lExtending downward from this rock shaft is an arm 123` formed with a slot into which projects a pin on the upper end of a curved lever: 124 hung loosely upon a transverse v shaft 125. When the aforesaid vibrating rod 44 is rocked downwardin the manner previously described to carry the links 41 mto mesh with their segment plates 45, this cross rod444 strikes the aforesaid lever 124 and thereby operates throu hun arm 123 to rock said shaft 122 and t creby rock all of the arms- 121 upward to release the key detent 31 from engagement with their depressed keys and allow the keys to spring back to their normal positions.. It will also be apparent from Fig. 6 that when any key is depressed, the shifting of its detent late will rock th'e shaft 122 and thereby t ow the rearward end 126 of the lever 124 into the path of a projection 127 fast upon the upper revolution shaft 28 so as to lock said shaft of the machine from operation while a ke is being depressed. 0f course when 40 the e detent returns to normalposition to latch the key in depressed position the lever 124 returns to normal position when its end 126 isout of the path of the projec-V tion 127 thus permitting further operation of the machine as soon as the key is completel depressed.

In cator meckam'sm.-.The indicator .mechanism is such as to rovide for the movement of the rotary indicators from one v differential position to another without'the necessity of the return of the indicators to zero osition at each operation. Alink 130 (see igs. 3 and 3*) is pivotally attached to' the up er end 131 of a swinging link 132 pivote upon the side of the rack arm-752. The rearward end of the link 130 is pivoted to an indicator rack bar 133 carrying at its upper end a. rack`meshing with a pimon 134 fast upon the side of a corresponding indi- 50 cater 135, and suitable cross gearing being provided for indicating at the front and at the back of the machine. At the middle of the link 130 is -a pin 136 and this pin is actedv upon by two cams one oi which 137 is fast to the upper operating shaft 27 and correspond to the values ofthe operating shaft 28. As soon as the rack bar 52 is positioned by the setting of its, corresponding segment 46 as previously described,

the rack ,bar is locked 1n adjusted position by an alining pawl 139,V and then the operation of the machine causes -the cams 137 and 138 tobring the pin 136` to acertain fixed point so that the rearward end of the lever is positioned differentially accordin to the position which the forward endof t e lever has assumed by the setting of the rack bar 52, and in this manner the 'indicators are set dierentiall to positions controlled by the setting of t e rack bars521which ositicns eys epressed. This indicator setting mechanism' is fully described in the aforesaid co-pend. ing application and it is thought the same will be'fully understood-without further reference thereto in the present application. The locking pawl 139 is suitably actuated by mechanism not shownherein -to lock the rack bars 5.2 -vin'set positions and unlock the same lattheprop'er oints in the operation of.v the machine. pawls 133'L are also provided for locking the indicator rack arms 133- in osition at the roper time, the mechanism or operatinget ese pawls not being shown herein but ing of any ordi- 'nary'and suitable form.

' Grand total wanten-The grand total counter comprises a series of registering wheels 140 (see Fig. 3) which are mounted in av vertically reciprocating carriage 141 which carriage of itself slides in an oscilf lating frame 142 pivoted to swing upon the po' t 143. The counter carriage 141 is reci rocated down and 'up at each operation o the machine by means of arms 144 suits ably pivoted at the rear of the machine and carrying pins 145 extending into cam grooves 146 formed in disks fast upon the aforesaid operating shafts 27 and 28 softhat upon each operation of the machine the counter is carried down over the aforesaid rack bars 53 and the counter is actuated to the extent corres onding to the dierential positions of sai rack bars 52. The counter is thrown into engagement with the rack teeth 53 upon the downward reciprocation of the counter and is thrown out of engagement upon the" upwardreciprocation, this-en agement and disengagement being effected y the swingv` ,ing o the entire frame 142 which is eiected by means ofan arm 147 (see Fig. 7) fast u on the rock shaft 125, which shaft is suita 1y rocked at each operation of the machine to swing the frame 142 rearward andv carry the counter into engagement with these actuating racks., This general method of setting these rack arms 52 and operating the counter in this manner by carrying the same downward overthe racks is similar'to that set forth inthe patent issued to Thomas 'nsl Carroll, No. 751,611, dated Feb. 9, 1904, and reference may had to said' patent for a fuller description of the details ofthe counter mechanism. This rocking of the shaft 125-to carry the counter frame 142 rearward so as to cause the total counter to be actuated by the rack 'teeth' 53, is effected by mechanism shown in Fig. 11 which mechanism v the will however be described subsequently in connection with the throwout mechanism co/ntrolled by the adjustable lever which positions the multiple counters for operation, the arrangement being such that when certain of the multiple counters are brought into operative positions for the registering of special transactions which do not represent cash transactions, the grand total counter would be thrown out of operation so that said counter uwill represent simply the grand total of cash transactions.

Multiple counters.-The multiple counters comprise a plurality of independent registerin lwheels arranged in sets each of which constitutes a counter, these counters 150 ('see Fig. 8) being arranged around the-outside circumference of a circular carriage or reel 151. This reel is mounted to turn upon an axis 152 and is rotated by means of a. differentially adjustable setting lever 153 moving over a scale 154 rovided with notches for the different setting' positions. This lever mounted upon a stub shaft 155 (see Fig. 7) and carries a circular disk 156 formed on its lower riphery with a segmental rack meshing wit a pinion 157 fast upon thevaxis of the multiple counter reel so that the movements of the lever 153 will position the reel and bring any desired one ofthe plurality of counters into osition to'be actuated by the aforesaid setting racks 58. In the present instance these counters are shown twelve in number, nine of the same being adapted to give separate totals for the transactions of nine clerks and the other three counters being for the purpose of securing totals of the special transactions such as Charge, Received-on-account, and Paid out.

The aforesaid clerks keys 21 (see Fig. 1) are nine in number and for each c1erk s key there'is a corresponding setting position of multiple counter setting lever 153, being with the top notch of the late 154 or clerk A, the second notch or clerk B and so on, this extent of movement of the lever 153 being sufficient to bring the f various clerks counters into proper position tofbe actuated. Inorder to compel the operation of the clerks key 21 corresponding to the setting position ofl the lever 153, the interlocln'ng mechanism shown 1n Figs. 9 and 9 is rovided. Fast to a collar surrounding txe aforesaid stub shaft 155 and rigidly connected to the lever 153 is a pinion 160 which meshes with a rack bar 161 pivoted upon the upper end of a key detent 'plate 162. This key detent piane 162 is formed with a series of notches 163 and in the normal position of the plate as shown' in Fig. 9aonly one of these notches is in alinement with its corresponding pin 164 projecting from the side of the shanks of the clerks keys 21. When however the lever 153 is moved from its upper position in which only clerk As ke canv be depressed, the movement of the rac bar 161 shifts the detent plate 162 longitudinally in the direcscale 154' while all the other notchesare out of alinement with their respective key pins 164. This same condition obtains for each one of the different positions of the setting lever 153 corresponding to the nine clerks so that all the clerks keys are locked except the one corresponding to the setting position of the lever. However since it is desirable when the setting lever is setv for the registration of any one of the special transactions, to Iesrmit the operation of any one of the cler keys in conjunction therewith, mechanism is provided which accomplishes this purpose as follows. The detentplate 162 is ormed at each end with cam slots 165 which are engaged by stationary pins 166 which serve to guide the late in its longitudinal. I

movements. When owever the setting lever 163 has been turned so far toward its lower position as to get. beyond the region of the nine clerks positions, the detent plate 162 at this point is shifted so far forward that the bent portion of the slot 165 now comes in contact with the ins 166 and the entire detent plate 162 is t K ereby depressed transversely to its own length, and this extent of depression is enou h to carry the entire detent plate below t e path of travel of the aforesaid key pins-164 sothat any one of the clerks keys can now be operated in conjunction with the'operation of any onev of the special transactioncounters. `A

In order to lock the-setting lever when any one of the clerks keys is depressed, mechanism is rovided shownI in Fig. 7, comprsing a loc g lever. 170 pivoted at 171 and formed at its rearward end with a slot 172 having a short bent ortion at the forward end' of the slot, an the lforward end Aof the locking lever giprovided' with a locka pin 175 which projects into the aforesaid slot 172, and when any one of the clerks keys is depressed, the rearward movement ofA the lever 35 causes the pin 175 to act upon the locking lever upon the moveiso 4"the operation of the machine the rearward with the setting of the amount indicators;

ment of this clerks setting lever 35 soV raise the rearward portion. of the locln-g lever and depress the locking head 173 into;

- positions of the lever 153v according to whichever of these three positions the lever may occupy, and thereby the bell crank segment engagement with the particular notch which has been brought into alinement therewith according to the setting position `of the lever 153, and thus as soon as a clerks key has been started to be depressed, the multiple counter setting leverv 1s securely locked i'n 1 This same locking lever 170 has 1 extending rearwardly therefrom an arm 176 position.

which normally stands in the path of a pin 177 carried upon a disk fast upon the upper revolution shaft 27 so that this Yarm 176 normally locks the shaft 27 from movement clerks keysis depressed lwhereupon the arm v 176 is withdrawn from locking position in front of the pin 17 7 uponthe rocking movement of the locking lever 170.v

In order to lock the multiple counter reel as soon as the machine has started, the devices shown -in Fig. 2 areprovided comprlsing a locking disk 180 fast upon the shaft 152 which carries the multiple counter reel, this disk being formed with notches 181 arranged to be engaged by a locking pawl 182 the rearward end of which eX- tends into a notch 183 formed in a disk fast upon the aforesaid shaft 68 so that upon end of the locking pawl 182 will be forced outof the notch 183 and the forward end will engage whichever notch 181 has been brought into alinement therewith according to the setting position of the lever 153 so that the multiple counter reel will thereby be securely locked until the machine has been completely operated when the pawl 1,82 again springs back to normal position shown in\-Fig. 2. l

For the purpose of setting a special indicator in connection with the movement of the multiple counter setting lever 153 to any one of the three lower positions representing the three special transactions Received on account, Charge and Paid out the aforesaid shaft 152 upon which the multiple counter reel is mounted has fast upon it a disk 190 Fig. 7 formed with a cam groove 191 into Awhich projects a pin 192 carried upon an arm 193- which arm is fast to a bell crank segment 194 similar to the pneviously described bell crank segments 46 which are utilized in connection with lthe amount keys. This bell crank segment 194 meshes with a rack bar 195 for the purpose of setting the special indicator 196, and the method of setting the indicator is the same as that previously described in connection Ewith Fig.

the grand total counter frame 142 rearwardto cause the counter to mesh with the oper-. l.ating racks 53. Pivoted loosely'upon this same shaft 125 is a bell crank lever 209 ,(see

but it will he observed that the shape of the cam groove'191 is such that the arm 193 is not cammed downward until the setting lever 153 has been rotated far enough to l www bring. the lever tofv the' first one of the' three lower positions, and then the segment 194 is moved 'differentially for these three lower 194 'lspositioned to prepare forthe setting of the special indicator to display the proper indication to correspond w1th the special transaction setting position of the lever 153.-

Throwout c0zmter.-Since the above mentioned three special transactions are not cash received transactions, it is desirable to throw out the grand total counter when the setting lever 153 is moved to any one of and thus locks the machine untll one of the such three, lower positions, and this is accomplished by means of the mechanism shown in Fig. 11, comprising a disk 200 fast upon the aforesaid-shaft 152 which carries the multiple counter reel, which disk is fforlned with a cam groove 201 into which projects a pin 202 carried upon the forward end of a bell crank lever 203 the upper end of which bell crank lever carries a pin 204 projecting into a slot 205 formed in the lower end of a coupling lever 206. This coupling lever is pivoted at its middle point 207 to the enlarged head of an arm 208 which is fast to the aforesaid rock shaft/125 which as reviously described in connection carries the arm 147 for throwing Fig. 11) the rearward end of which carries a pin 210 projecting into a cam groove 211 formed in a disk fast upon the lower operating shaft 28; and the forward end of this bell crank lever carries a pin 212 which projects loosely through a slot 213 formed in the enlarged head of the arm 208. The l aforesaid coupling lever 206 is formed at its upper end with a hook 214 adapted to engage the aforesaid pin- 212 when the parts are in the position shown in Fig. 11. When the parts are in such position, the operation of the machine will cause the rearward end of the bell crank lever 209 to be lowered and this will raise the forward end so that the pin 212 being engaged by the hook 214, will lift upon the coupling lever 206 and since this lever is pivoted to the enlarged head of the arm 208 which is fast to the aforesaid rock shaft 125, this resultsin the rocking of said shaft to rock the arm 147 (see Fig. 7 to carry the grand total counter into mesh with its operating racks and then carry the counter out of mesh upon the return reciprocation of the counter. When however the multiple counter setting lever 153 is turned to any one of the three lower positions for the special transactions, the disk 200 is turned to such position that the forward end ofthe bell crank lever 203 will be cammed upward andv the coupling lever 206 `will be swung about its pivotal point so as to 'uncouple its upper hook end 214 from engagement with the pin 212,. so that now upon the rocking of the bell crank lever 209,

' the pin 212 will no longer engage said coupling lever and of course will thereby have no effect upon the arm 208 but will simply slide idly upward in the slot 213 in said arm rock shaft 125 so that the grand total counter will not be rocked into engagement with its operating racks and thus will not be operated in connection with the registramultiple counters.

Zero resetting mechanism-In order to reset to zero the various counters which are mounted upon the multiple counter reel as previously described, the reel is rotated to bring each one of the counters successively into a particular position where access may be had to the same for the purpose of resetting it to zero, all of whlch mechanism and the various locking devices connected therewith will now be described. As shown in Fig. 2, each counter is mounted upon its turn-to-zero shaft 220, the end of this shaft being formed with slots 221 adapted to receive the projections 222 (see Fig. 2") formed on thel end of the zero'resetting key 223 softhat when the projections engage said slot the turnin of the key will rotate the zero resetting s aft 220 and said shaft is provided with the well known oove construction coperating with sprmg-pressed pawls on the counter wheels to pick up said pawls and reset all of the counter wheels to zero when the zero resetting shaft is given a complete rotary movement, this particular mechanism not being shown herein as 'it is already well known 1n the art. The endof each zero resetting shaft 220 has fast upon it a locking disk224 formed with a .45 cut away portion 225 which conforms to the circular periphery of a disk 226 which disk isj-stationary being co-axially mounted with reference to the multiple counter reel and servesas a controlling disk to control the 50 resettin'gof the various counters to' zero.

This disk is formed with a rectangular cut away portion 227 which is of such width that when the multiple counter is rotated to bring any particular counter into position 55 in alinement with said recess 227, such for example as the counter 228 in Fig. 2*, then the locking disk 224 of this counter lis no 'longer locked by the periphery of the controlling disk 226V arfd consequently 'the 60 counter may beresetto zero. When a counter is thus brought into position to lbe turned to zero, access to the zero resetting shaft is had through an aperture 230 (see Fig. 2) formed in the inclosing casing or 55 side frame 231- of the machine, but this aperwithout having any rocking effect upon the tion upon any one of the special transaction turei'230 is arranged to be closed by a guard having anv operating handle 233 and j being pivoted at 234 to the aforesaid stationary disk 226. The guard is guided in its oscillatory ,movements about its pivotal point by means of a pin 235 playing in a slot 236 formed in said guard. The guard is also formed with an aperture 237 and when the guard is thrown into the position shown in Fig. 2% this aperture is brought opposite the -zero resetting shaft for the particular counter which stands in alinement with the aforesaid recess- 227, so that the zero resetting key may be inserted through the aperture 230 formed in the inclosing casing and also through the aperture 237 formed in the guard and thus the counter may be reset to zero. When however the guard is thrown to its upper position, the solid portion of the guard closes the aperture 230 in the casing and prevents access being had to the counter toreset the same to zero. The guard 232 is also formed with a slot 240 into which projects a pin 241 block 242. This block slides in the aforesald rectangular recess 227,

formed on a sliding and it will be seen from Fig. 28L that when the guard is in the lower posltion permitting access to the particular counter brought into alinement with said recess 227, the block 242 is at the lower end of said recess and the upper ed e 243 of said block is'so far below the loc disk 224 of this counter 228 that it `does not present any obstruction to the zero iresetti movement of this particular counter. en however the guard is moved to` its upper position, the swinging movement of the guard will cause the block 242 to travel outward in the recess 227 until the upper edge 243 reaches the cut away portion of the locking disk 224, this in fact filling out the periphery of the controllingV disk 226 so that now it 1s impossible for the counter to be reset to zero even though access could be had to the zero resetting shaft by other means, and furthermore the filling out of the periphery of this disk 226 by the block 242 prevents the various counter disks 224 from catching on the walls of the recess 227 when the counter reel is operated. Thus it will be seen that the-controlling disk 226 is common to all of the counters to prevent rotation of their zero resettin shafts except for the one counter which m in alinement with the recess 227 'provided Asaid recess is free from obstruction by reason of the guard having been lowered to depress the block 242; and of course each counter as it is moved into position to be operated upon by the previously described operating racks also has its zero resetting shaft locked by this common controlin disk 226. The guard 232 is also formed wit a hook 245 (see Fig. 2*) which -when the guard is moved to lower position to permit the resettingto zero of the counter, engages over the zero resetting shaft of the counter directly below the counter which has been ositioned for zero resetting, and b lockmg this counter to the guard, the entire reel is locked from movement so that the setting lever cannot be rotated.-

In connection with the resetting to zero of the various multiple counters it is desirable to have' some means which will compel 'a rotation of the vzero resetting key to a slight extent beyond the normal full rotation so as therebyv completely to insure the wheels being all returned to proper zero positions. The mechanism for accomplishing this and certain other purposes is shown in Fig. 2. Pivoted at 250 upon the inclosing casing of the machine is a plate 251 which is spring-pressed forward by means of a spring 252. This plate is formed with a circular aperture 253, this aperture however being still further cut away at 254 in a rectangular formed notch which notch is just wi e enough to permit the passage therethrough of thev pin 255 (see Fig. 2b) formed on the side of the zero resetting key 223. Thus whenv the resetting key is inserted into the aperture 253 .of the pivoted plate 251, the key has to be in such position that the pin 255 is in alinement with the notch 254. There is a slight space between said pivoted plate 251 and the side frame 231 so that as soonas said key pin 255 has passed through the notch 254 the key pin may rotate freely between the inner side of said plate and the outer, side of said side frame; but in order'for the projections 222 of the zero resetting key to be brought properly into alinementwith their corresponding notches 221 formed in the zero resetting shaft, it is necessary to. give the key a slight turning movement toward the right or clockwise in Fig. 2, in which event the aforesaid pin 255 strikes a spring-pressed pawl 256 pivoted upon the inner face of the pivotedA plate 215, and -the bearing of the pin 255 against this pawl 256 forces the pawl against a stop pin 257 projecting from the plate 251 and this causes the swinging rearward and downward of the entire pivoted plate 251. Of course this swinging movement is very slight and just enough to permit the key properly to engage the turnt-zero shaft, and as soon as this engagement has been effected the key is rotated toward the left in the direction of the arrow shown on counter 228 in Fig. 2, so that the pin 255 is now withdrawn from contact with the pawl 256 and the plate 251 is free to spring forward to normal position, but this brings the notch 254 back to normal position so that upon the complete rotation of the zero resetting key the notch 254 would be a slight distance in advance of the key pin 255 so that the key cannot be removed until the key is rotated a slight movement farther to bring the key pin 255 into alinement vwith the' notch 254 and thus permit the withdrawal of the key, and this insures the complete setting to zeroof the counter wheels upon this completionof the zero resetting movement of the key.l It will be 'completely turned. The presence of this vkey stop device mounted on the casing obviates t-he necessity of having such a stop device mounted on each counter where each counter is separately reset to zero, so that by thismeans any articular counter may vbe brought into position to be reset to zero and this one stop device serves for all of the independent counters to arrest the key in each case when the same has been given its proper zerol resetting movement. It will be noted that the counter shaft has been given slightly more than a completerotation'but this is compensated for when the arm 233 moves upward as shown in Fig. 2a when the sliding block 242 moves upward and abuts the disk 224 and returns the same to normal position.

Transfer dem'0es.-In connection with the operation of the multiple counters, a novel form of transfer mechanism is provided as shown in Fig. 8. Mounted upon each counter wheel is an ordinary form of tripping disk having a tripping nose 260. This nose 260 is adapted to strike the nose of a tripping pawl 261 which pawl is loosely pivoted at its middle point upon the same transverse shaft 64 upon which the aforesaid arm 63 is mounted which carries the vibrating rod 62 upward and downward as hitherto explained. The rearward end of this tripping pawl or lever 261 has extending laterally from it a projection 262 coperating with a latching pawl 263 pivoted loosely upon the shaft 264. The forward upper edge of the tripping pawl 261 is arranged to strike a pin 265 projecting latery'ally from a transfer dog 266 pivoted at its middle point on the side of the registering rack bar 58 for the wheel of neXt higher order. This transfer dog is normally held in horizontal position as shown in Fig. 8 by a spring 267, the pivotal movement of the dog being controlled by a stop pin 268 projecting frmthe side'of the dog into an enarged aperture formed in the adjacent rack Projecting from the arm 63 which as above described is pivoted on the shaft 64 and is utilized for vibrating the cross rod 62, is a izoA cross rod 270 which extends across the upper edges of the rearward ends of all of the aforesaid tripping pawls 261. In the normal position of the 'parts this cross rod bears against said transfer pawls to hold the forward ends thereof raised and out of the path of the tripping pin 260 of the counter, so that in this normal position of restthe multiple counter reel is free to be rotated whereas of course if the. tripping pawls 261 stood normally ready to be engaged by the tripping pins of the counter, the multiple counter reel could not be operated without tripping said tripping pawlsand for-this reason the tripping Apawls are normally held raised above the counter wheels. When however upon the operation of the machine, the aforesaid vibrating rod 62 is carried downward by meansof vthe rocking of the arm 63 for the purpose of carrying the rack bars into ..,1`nesh with they counter, this upward movementof the rear? ward end of the arm 63 raises the cross rod 270 from engagement with the rearward ends of the tripping pawls and permits their forward noses to drop into position to be tripped by the tripping pins of the counter, the tripping pawls being spring-pressed to such positions by means of springs 271 suitably seated in the cross bar of the machine. However this movement of the tripping pawls is still further dependent upon the aforesaid latches 263. It will be seen that the rearward edge of each latch 263 is formed with a lower shoulder 272 and an upper shoulder 273, these two shoulders being very near together. In the normal position of the parts, the aforesaid lateral projection 262 of the tripping lever is seated under the lower shoulder 272 of the latch 263 so that therearward end of the tripping pawl will be heldlatched down in'this position even though theaforesaid cross vrod 27 O has been raised to permit the rearward end of the pawl to spring upward and carry the forward end downward into engagement with the counter. In order still further to release the tripping pawl, 'a rocking frame274 is provided, being pivotally mounted upon the aforesaid shaft 264 upon which the latch pawls 263 are' pivoted. vExvtending upward from this frame is anarm 275 carrying4 a pin 276 projecting into a cam groove 277 formed in a disk fastupon the lower operating shaft 28, so thatv upon the operation of the machine thisrock frame latched under the lower shoulder 272 of the latch pawl 263, yet upon the operation of the machine the rockframe 274 is rocked downward and strikes upon shoulders 280 of the latch pawls and' carries -their rearward ends forward slightly to permit the tripping pawls to spring upward so that the lateral projections 262 now rest under.l

the upper shoulder 273 of the latch pawls and thus the forward ends of the tripping pawls are in position to bet-ripped by the counter wheels in the ordinary manner. Y In themeantime the rock frame has ascended sufficientlyto free itself from engagementy with ,the shoulders 280 so that now 'if upon the forward movement of any registering rack 58 its'counter wheel is turned beyond the 9, then its tripping pin 260 will strike the depressed forward endof the tripping pawl 261 and raise the same, thereby depressing the rearward end and Whereupon the latch pawl 263 springs rearward to cause the lower shoulder 272 to spring over the later projection 262 and hold the' tripping pawl latched in this position. Now upon the forward movement of the rack bar of the next higher order, its pin 265 carried by its transfer dog 266 will strike this raised tripping pawl 261 and ride up upon the same thereby rotating the dog 266 upon its pivotal point and bring the rearward end of said dog into the path of' a transfer operating arm 2.90, which is spring-pressed rearward by means of a springv 291. There are' afseries of these transfer operating arms 29.0, one for each rack bar, and they are piveted on the .rod

291 and carry rearwardly arms 292 provided with pins 293 acted upoirby cams 294 which are spaced at different inp tervals around the operating shaft 68 so that the transfer operating arms will be successively operated at each operation of the machine in a well known manner. If

any transfer dog 266 has been turned upon its normal movement of registration. Near the end .of the operation -of the machine of course the rack4 bars 58 Aare rocked upward-v a ain out of mesh with their counter as hitherto described 'and the cross rod-270 iS at the samev time carried downward to depress the rearward ends of all cfg-the tripping pawls so that the parts can .assume their normal positions as shown in Fig. 8 with the lateral projections 262 resting in under the lower latching shoulders 272 of the latching pawls. Whenever the rack 5, bars are given an additional transferring movement forward, it becomes necessary to restore them backward this unitary distance at the end of the operation of the machine, and this is done by means of projections 295 10 formed on the rearward side of the latching pawls 263, which projections bear .against pins 296 projecting from the -side of the corresponding rack bars 58; and the shape of the aforesaid cam groove 277 which rocks the aforesaid rocking frame 274, is such that at the end of the operation of the machine said rock frame is given an upward movement and by bearing against the'shoulders 282 of the latch pawls carries the downward portions of said latch pawls rearward a slight extent thereby causing the projections 295 to bear against pins 296 and restore to normal position those rack bars which have been given a unitary transfer movement forward in excess of their normal movement of registration. rllhe rock fra-me 274 is also provided with a locking extension 297 arranged to engage teeth 298 formed in the registering rack bars to lock said bars in position when the rock frame is moved downward. f

Special puntera-By referring to Fig. 1 it will be seen that the various counters carried upon the multiple Vcounter reel have eight counter wheels mounted co-axially and the three left-hand counter wheels designated as 300 are intended to be utilized as special counters to have one unit added thereon each time that the corresponding clerks 4o counter or special transaction counter is operated, the remaining eight wheels being the ordinary main counter wheels of the counter. The method of actuatingthese special counters is shown in. Fig. 10. A special counter operating bar 301 is suitably mounted at its rearward end upon the aforesaid cross shaft upon which the registering bars 58 are mounted, and at its forward end is formed with a slot through which the 5@ aforesaid vibrating rod 62 extends so that when said rod is rocked downward to carry the rack bars into mesh with their counter, the operating bar 301 will also be carried downward, and this will carry downward 55 into mesh with the special counter 300 a three-pronged pawl 302 mounted upon the side of the operating bar 301. rllhis threepronged pawl is of a well known torni the diderent prongs being of diderent depths 6@ to coperate with notches of diderent depths of' the special counter wheels so as to provide a transfer from one wheel to another in a well known manner.. @t course the special counter which this pawl meshes with when the operating bar is thrown downward is the one which is on the same shaft with the counter 150 operated by the rack bars. This operating bar 301 is rocked forward at each operation of the machine so as -to cause the pawl 302 to give a unitary movement to the unit wheel of the special counter; by means of an arm 303 pivoted upon the aforesaid shaft 291a and having a rearwardly extending arm carrying a pin 304 operatedupon by a cam groove 305 formed in a disk fast upon the shaft 68 so that near the end of the operation of the machine the arm 303 is thrown forward and acts upon a pin 806 projecting from the bar 301 to force said bar forward to operate thespecial counter.
